With his bioinformatician Michael Crusoe he published a software paper in F1000 Research and included all authors which contributed to the code hosted on GitHub (even authors that only corrected typos):http://f1000research.com/articles/4-900/v1
Note, F1000 Research follows a post-publication peer review model, i.e. the paper hasn't undergone peer review yet.

In life sciences your reputation is basically build upon authorships and the position of the authorship on the paper. The authors more to the front (supposedly) contributed more significantly to the study, except for last authorship which usually is reserved for the PI (aka the person who procured the funds). Of course the impact factor of the journal is also hugely important.

Ask Open Science used to be called Open Science Q&A but we changed the name when we registered the domain ask-open-science.org. Everything else stays the same: We are still hosted by Bielefeld University Library.
